SWIVEL ROPE SOCKE'I'.

Application filedJuly 17,

My invention relates to 21 swivel a11d 11101e pa rticularly to a swivel 111e111be1 for mounting 011 a1 rope 01' cable.

It is a purpose of my invention to provide a swivel men1ber that is particularly adapted 101 use 111 connection with 011 well apparatus and which is provided witl1 a'n internal swivel n1ember secu1ed to the endportion 013 tl1e flexible men1ber carrying tl1e swivel and wl1icl1 is rotatable witl1in the body portion 01 the device.

It is a furt-her purpose of 1ny invention to provide means f01 lubri'catingtl e member seeured to tl1e encl of tl1e flexible n1ember so tl1at the san1e. Will tur11 readily within the socket or bearing provided for tl1e same 111 tl1e body 111e111be1j.

It is a fu1tl1ei purpose of tl1e inventiont o provide means externally of ehe body portion and secu1ed 10 the flexible member f01 providing a tigl1t jointbetween tl1e flexible- 111e111ber und t-l1e body portion to tl1us prevent escape of lubriczmt 1'1:o111 tl1e body portion and entrance of fo1eign matterinto tl1e body portion.

It is a further purpose of th'e inventi0n to provide meang externally of tl1e body portion of tl1e swivel for preventing 'endwise movement of tl1e internal swivel men1ber witl1in a socket, which is objectionable as itcauses enlargement o1 the svvivel member so that it Will fit so tigl1tly in its bearing tl1at itwill 110t rotate therein. Seid 111ea11s pref erably co1nprises a pai1 of relatively movable n1embers, 011e of whioh is adjustable relative t0 tl1e otl1er and botl1 of wl1icl'1 are adapted to be independently secured to the flexible n1en1ber so that by adjustment of said 111e111- be1s relative to each otl1er, -the inner 1otatable 111ember is b1ought into close engagement with tl1e end of its bearing within the body portion to tl1us a void axial movement of tl1e rotectable member within tl1e bearing. Furtl1ern1ore, by providing die rotata ble me111ber witl1in tl1e housing and tl1e means carried by tl1e flexible member exteriorly of tl1e housing und rotatabl'erelative eo tl1e l1ousing, l'l1e flexible n1ember is hel'd' substantially in axial alignment witl1 tl1e passages tl1terefor in the housii1gevoiding undue wear of said flexible men1berby engagement with tl1e. wa*lls of tl1e passage'.

Other objectg and advantages of; theinvem tion Will appear-as tl1e descripti0n of Cl1e 11; companying drawings proceeds. However; I desire to have il= distinctly understood that 1926. Serial .I\To. 123,025.

Referring in detail tothe draWings:

My improved swivel memloer comprises a body portion l0-wl1icl1 is provid'ed wit h the flattened faces 11 o11 opp0site sides thereof for engagernenis of 21 suitable cool such as a wrench therewith for turning the men1be1x 10. Seid 111e111be1 10 is provided Witl1a1reduced upper end portion l2 and Wii:l1 an in-.

te1nally threaded tapering opening 13 at theopposite e11d thereof Wl1ich isadapted 'f01 connection witl1a threaded pi11 011 a men1ben carriedbythe swivel, such as a cool or othe1 device tl1at is tobe supported by a: suitable flexible member in the usual wann-(er. A

substantially cylindrical passage 14.. leads:

fron1 the internally threaded portion 13 to tl1e internally threaded ortion 15 Witl1 whicl1 a plug 16 serew-threadedly engages. Lea'ding f1om tl1e tl1readed po1tion 15 towa-rd tl1e interior of the-body portion 10 is an elongated cylindrical bearing portion 17- 2111d from said bearingportion a assage 18 of reduced diameter leadsto tl1e end Portion 19 01: tl1e body portion10,e sl1oulder being provided at 20 between the passage. 18 and tl1e bea1ing portioi1 17. ing lubricanfi assage 21 lezrdi-ngoutwardly fromehe bearingortion 17 is provided Wi-tl1 an internally threaded portion 22 that sc1ewthreadedly engages with t-he plug 23 Which ma.y be removed for insering lub1icantwitl1in tl1e bearing portion 01 chamben A latenally extend- 17 by an suitable ineans for inserting lub1icant un er ressure.

Mounted 101 rotat1on Within tl1e bear1ng chalnber 17 is the internal swivel 1ne1nber 24 whiel1 has a subtantially cylinclrical outer Wall portion and wbich is providecl with a tapering bore 24' increasing gradually in diameter frorn the Sma1l end 25 thereof to the large end 26 thereof. A

: flexible member 27 is mountecl Wihin the member 24, being held in place therein by means of suitable 1netal of l0n fusing point, such as lead, indicatecl by the ninneral 28, Which keys tl1e member 27 within the taper T ing bore 24' to thus finnly secure sai cl flex ible member to the rotatable me1nber 24.

V The flexible member 27 extencls threugl1 the passage 18 and has the collars 29 ancl 30 mounted thereon externally of the body portion- 10. The members 29 ancl 30 are helcl in Position respeetively on theflexible meinber27 by.means 0f the tapering pins 31 and 32 mountecl in correspondingly tapering sockets in the me1nbers 29 ancl 30, saicl pins wedging the flexible 1ne1nber 27 into firm engagement with tbe Wall portions -of the longitudinally extending passages 33 ancl 34 in the members 29 and 30 respeetively.

The member 29 is provicled with a downwardly extencling annular flange portion 35 which. is provided with internal screw threads 36 that engage With the externally 'screw threadecl annular flange portion 37 provided 0n the member 30 ancl extencling upwardly therefro1n. The flange portion 37 provides a socket 38 in tl1e upper end 01 the member 30 within which the compreesible gasket 39 is seated, seid gasket engaging with the annular rib 40 provided on the mernber 29 surrounding the opening 33 theiein at the lower end thereof. The 1ne1nbei 30is furthermore provicled with an an- 'nular groove 41 in the lower end thereof which is eoncentric with the opening 34 and within which is seatecl a compressible gaeket 42. The encl portion 19 of the booly portion 10 is providecl with an annular rib 43 tha.t is c0ncentric with the opening 18 ancl that is adapted t0 fit within the groove 41 so tbat while the members 30 and 29 are rotatable relative to the me1nber 10, the movement thereof Will be guided so that the flexible this has been clone, tl1e flexible rnember 27 is clrawn up into the body ortion 10 until the encl thereof engages With the sboulcler 20. The plug 16 is tl1en serewecl into positi0n by any suitable t00l engaging With any suitably shapecl projection 44 thereon ancl after this has beendone the 1neinbers 29 and 30 which have been placecl on the meinbei 27 previous t0 pulling the salne through the bocly portion 10, are brought down into engagement with tl1e body portion 10. The 1ne1nber 29 is then roatecl'rela-tive t0 tbe 1nember 30 to compress the gasket 39 als much as possible, whereupon the pin 31 is driven into place to flnnly engage the 1ne1nber 29 witb the flexible 1ne1nber 27. After this l1as been cl0ne tbe n1ember 30 is rotatecl relative t0 the 1nember 29 50 1nove the same away fro1n the member 29 01 toward the encl 19 of tbe body pertion 10. Upon cloing this the flexible mexnber 27 is. draWn tigh so as to take up any play that might exist between the member 24 anal the member 10, ancl after this has been Clone the pin 32 is driven into position to flnnly seeure the 1nember 30 130 the flexible member 27, tlms preventing relative rotation 01 tbe members 29 ancl 30 und holcling the ame in adjustecl position. The plug 23 is ben removed ancl l'ubricant is injected into be cbamber 17 tbrough tbe passage 21 by any suitable pre:sure meane, after which be plug 23 is replacecl and ehe clevice is re'acly 1"01 use. The gaskets 39 and 42 Will tl1en be compressecl so as co provide a tigl1t joint between the 1ne1nber 30 and the body portien 10, ancl between the mexnber 29 and the flexible 1ne1nber 27. At the sa1ne time a swivel bearing is provicled within the bocly portion 10 -between tl1e m-Ember 23 and the Wall ortion of the bearing cba1nber 17 ancl externally of the 1ne1nber 10 between the annular rib 43 ancl the gioove 41 in the 1nem bei 30.
